Silicone products are a very high-quality product that has applications in many fields. In addition to daily life applications, the application of silicone products in industrial manufacturing is also very common. Silicone sealing ring is the application of silicone products in industrial manufacturing and other industries. It is an excellent silicone product. Today, the editor will take you to understand the advantages and disadvantages of silicone sealing rings. Let‘s take a look together.

Advantages of silicone sealing ring

1. Heat resistance: Silicone has much better heat resistance than ordinary rubber, and can be used almost permanently at 150 ° C without any performance changes. It can be used continuously for 10000 hours at 200 ° C and for a period of time at 350 ° C.

2. Aging resistance: It remains yellow and does not fade after long-term use.

3. Safety: The raw material used is food grade silicone collagen material, and the product is colorless, odorless, and does not deform or produce harmful substances under high temperature conditions.

4. Widely used in applications that require heat resistance, such as sealing rings for hot water bottles and heat-resistant handles for pressure cookers. Cold resistance: Ordinary rubber ranges from -20 ° to -30 °, while silicone still has good elasticity at -60 ° to -70 °. Some special formulations of silicone rubber can also withstand extremely low temperatures, such as low-temperature sealing rings. Sealing performance: It has good sealing performance.

Disadvantages of silicone sealing ring

1. Poor tensile, tear and mechanical properties. At room temperature, its physical and mechanical properties are not as good as most synthetic rubbers (except nitrile silicone and fluorosilicone rubber), with low tensile strength and poor tear resistance. It is not recommended to use silicone sealing rings for working environments with tensile, tear, and strong wear conditions. Usually, only static sealing is used.

2. Not suitable for use in environments with work pressure exceeding 50psi. It is not recommended to use silicone sealing rings in most concentrated solvents, oil products, concentrated acids, and diluted caustic solutions.

3. Compared to other materials in terms of price, the manufacturing cost of silicone sealing rings is relatively high.

Silicone sealing rings have excellent properties such as heat resistance, aging resistance, and safety. Silicone sealing rings are an excellent product.
